What you have to do to get to this answer is to use the formula for the circumference of a circle. Once you have that, you need to know what percent of the circumference of the wheel is represented by 2 feet. Given that, you then need to multiply that percent by the number of degrees in a circle. Here are the steps:

The circumference of a circle is equal to pi times the diameter. Since the radius is .5 of the diameter, the radius here is 28 inches.

The angle of rotation and the distance traveled by the car when it makes a distance 2feet, is given by the fact that one rotation is equal 2pir has 360 degrees. Then by the same proportion 2 feet distance contain how much degree.
